K&N 57i Air Induction Systems for Horsepower & Torque Gains

57i Air Induction Kits

K&N air induction systems replace your vehicle's restrictive factory air filter and air intake housing. K&N induction kits are designed to dramatically reduce air intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to pull in a larger volume of air than the stock OEM air filter assembly. More air means increased power and acceleration throughout the engine's RPM range. The K&N cold air induction filters on these kits are washable and reusable. Most of our air induction kits are easy to install with common household tools.
